Description

Technical Field

[0001] This utility model relates to the field of cable wrapping tape production technology, specifically a fixed-length cutting device for producing cable PE wrapping tape with automatic roll changing capability. Background Technology

[0002] PE wrapping tape is an insulation material widely used in the power cable industry. It is mainly made of polyethylene resin through a special process, and possesses excellent insulation properties, mechanical properties, and environmental adaptability.

[0003] In cable manufacturing, cable wrapping tape is an indispensable component. It not only acts as a protective and cushioning pad but also plays a crucial role in ensuring the cable maintains its round shape, preventing fraying. Since the wrapping tape is typically located between the core wire and the shielding layer, it also serves an insulating function. During the cutting process, due to the characteristics of its material, the wrapping tape maintains good tension, requiring extremely sharp cutting tools; otherwise, it is difficult to cut the tape smoothly. The wrapping tape is produced in rolls, requiring manual loading and precise measurement of dimensions. Therefore, based on actual usage, we have improved the existing technology described above.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fixed-length shearing device for producing PE wrapping tape for cables with automatic roll changing includes a base, a turntable mounted on the top left side of the base, and four sets of identical support legs connected to the top right side of the base. All four sets of support legs are located at the four bottom corners of a transmission assembly. The transmission assembly includes a transmission belt, with rotating rollers connected to both ends of the inner cavity of the transmission belt. Each set of rotating rollers is connected to the support legs via a connecting shaft. A column is connected to the rear side of the base, and an electric telescopic rod is connected to the top front side wall of the column. A lower pressure platform is connected to the outer end of the electric telescopic rod. A sliding support rod is installed through the bottom of the lower pressure platform, with its rear end connected to the outer wall of the column. The front end of the sliding support rod slides through the lower pressure platform and connects to a limit plate. A second electric telescopic rod is connected to the bottom of the lower pressure platform, and a cutting assembly is connected to the bottom of the second electric telescopic rod, with the cutting assembly located above the transmission belt.

[0007] Furthermore: A motor is installed on the top of the base, and the motor is located below the transmission belt. A drive wheel is connected to the power end of the motor. A belt is connected to the outer wall of the drive wheel, and the other end of the belt is connected to one of the rollers connected to the four sets of support legs. The roller passes through the support leg and is connected to a counting disk. A counting sensor adapted to the counting disk is connected to the support leg.

[0008] Furthermore: The top of the turntable is connected to a rotating column, and three sets of identical L-shaped plates are evenly arranged on the top outer wall of the rotating column, with a drum support rod connected to the outer wall of each set of L-shaped plates.

[0009] Furthermore: the cutting assembly includes a concave block connected to the second power end of the electric telescopic rod, a cutting motor connected to the right outer wall of the concave block, a cutting blade connected to the power end of the cutting motor through the outer wall of the concave block, and the cutting blade is set in the concave groove of the concave block, and a pressure plate is connected to the bottom of the left side wall of the concave block.

[0010] Furthermore: the transmission belt is uniformly provided with bosses, each boss including a large vertical plate and a small vertical plate arranged opposite each other, and a gap is provided between the large vertical plate and the small vertical plate.

[0011] Furthermore: the lower pressure plate is a trapezoidal rubber sheet.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This application document utilizes two sets of electric telescopic rods to facilitate the horizontal movement and cutting of the wrapping tape by the cutting assembly. Furthermore, during the pressing process of the lower pressure plate, the gap between the large and small vertical plates on the transmission belt allows the wrapping tape to be pressed into the gap while cutting, simplifying the cutting operation and providing a self-limiting function for the wrapping tape, allowing it to move with the rotation of the transmission belt. As the gap moves to the edge of the transmission belt, it automatically widens, automatically releasing the clamped wrapping tape. The use of a counting sensor and counting disc enables automatic control of the turntable's rotation, achieving automatic roll changing and ensuring controllable length of the cut wrapping tape.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model provides a technical solution: a fixed-length shearing device for producing PE wrapping tape for cables with automatic roll changing capability, comprising a base 1, a turntable 2 mounted on the top left side of the base 1, a power motor (a stepper motor) connected to the bottom of the turntable 2, electrically connected to an external power source via wires to ensure the rotational power of the turntable 2, and four sets of identical support legs 3 connected to the top right side of the base 1, with the four sets of support legs 3 positioned at the bottom corners of a transmission assembly. The transmission assembly includes a transmission belt 4, with rotating rollers connected to both ends of the inner cavity of the transmission belt 4, and each set of rotating rollers connected to the support legs 3 via a connecting shaft. A column 5 is connected to the rear side of the base 1, and the top front side wall of the column 5... An electric telescopic rod 11 is connected to the upper part, which drives the lower pressure platform 12 to move in the horizontal direction. The outer end of the electric telescopic rod 11 is connected to the lower pressure platform 12. A sliding support rod 13 is provided through the bottom of the lower pressure platform 12 to provide support for the lower pressure platform 12. The rear end of the sliding support rod 13 is connected to the outer wall of the column 5. The front end of the sliding support rod 13 slides through the lower pressure platform 12 and is connected to a limit plate 14 to prevent the lower pressure platform 12 from falling due to excessive extension and retraction of the electric telescopic rod 11. An electric telescopic rod 2 15 is connected to the bottom of the lower pressure platform 12, and a cutting assembly 16 is connected to the bottom of the electric telescopic rod 2 15. The cutting assembly 16 is located above the transmission belt 4.

[0020] In this application, please refer to Figure 1 The wrapping tape is placed on the transmission belt 4. The transmission belt is displaced by the drive of the motor 6. After reaching the designated position, the electric telescopic rod 11 drives the lower pressure table 12 to move, and the electric telescopic rod 2 15 drives the cutting assembly 16 to cut the wrapping tape in the horizontal direction.

[0021] Preferably, a motor 6 is installed on the top of the base 1 and is electrically connected to an external power source via a wire. The motor 6 is located below the transmission belt 4. A drive wheel 7 is connected to the power end of the motor 6. A belt 8 is connected to the outer wall of the drive wheel 7. The other end of the belt 8 is connected to one of the rollers connected to the four sets of support legs 3. The roller passes through the support leg 3 and is connected to a counting disk 9. A counting sensor 10 adapted to the counting disk 9 is connected to the support leg 3.

[0022] Preferably, the top of the turntable 2 is connected to a rotating column 201, and three sets of L-shaped plates 202 with the same structure are evenly arranged on the top outer wall of the rotating column 201, and a drum support rod 203 is connected to the outer wall of each set of L-shaped plates 202.

[0023] In this embodiment, please refer to Figure 1 Motor 6 provides the power source, driving belt 8 to rotate, which in turn causes transmission belt 4 to move. At the same time, sensor 10 records the data on counting disk 9 and sends it to the control system. The control system controls the start and stop of motor 6 through signal transmission, thereby setting a preset value to drive transmission belt 4 to rotate at the same angle, ensuring that the length of the wrapping tape cut each time is the same. When transmission belt 4 rotates to a certain length, the cutting component cuts the wrapping tape. Meanwhile, after the wrapping tape roll placed on turntable 2 is used up, the stepper motor under turntable 2 starts to rotate another set of wrapping tape rolls to the angle corresponding to transmission belt 4, and cuts the next roll of wrapping tape, achieving the purpose of automatic roll changing. This control system is existing technology and will not be described in detail.

[0024] Preferably, the cutting assembly 16 includes a concave block 161 connected to the power end of the electric telescopic rod 15. A cutting motor 162 is connected to the outer right side of the concave block 161. The power end of the cutting motor 162 passes through the outer wall of the concave block 161 and is connected to a cutting blade 163. The cutting blade 163 is disposed in the recessed groove of the concave block 161. A lower pressure plate 164 is connected to the bottom of the left side wall of the concave block 161. The lower pressure plate 164 is a trapezoidal rubber plate.

[0025] Preferably, the transmission belt 4 is provided with bosses evenly distributed. The bosses include a large vertical plate 41 and a small vertical plate 42 arranged opposite to each other, and a gap is provided between the large vertical plate 41 and the small vertical plate 42. The size of this gap is adapted to the size of the lower pressure plate 164.

[0026] In this embodiment, please refer to Figure 1 Figure 2 and Figure 3When the cutting component 16 contacts the transmission belt 4, the bottom two side walls of the concave block 161 contact the large vertical plate 41 respectively. At this time, the lower pressure plate 164 enters the gap between the large vertical plate 41 and the small vertical plate 42, which squeezes the wrapped tape from the transmission into the gap. This solves the problem of cutting errors caused by the tension of the wrapped tape. In addition, the wrapped tape squeezed into the gap also has a limiting function, which makes it easy for the transmission belt 4 to rotate and drive the wrapped tape to a certain distance. When this gap rotates to the edge of the transmission belt 4, the gap becomes larger due to the effect of the arc. At this time, the clamped wrapped tape automatically falls off. The operation is simple.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
